FRED F. HAFEMEISTER, OF CLEVELAND, OHIO, ASSIGNOR TO THE CLEVELAND SWITCH- BOARD COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

MOUNTING FOR PANEL BOARDS, ETC.

Application filed July 14, 1919. Serial No. 310,844.

concern:

Be it known that I, FRED FQHAFEMEISTER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Mountings for Panel Boards, Etc, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention relates to mountings for panel or switchboards and the like, and more particularly to one in which the individual parts comprising the mounting are adjustable with respect to each other.

In the usual type of mountings the board is supported in a housing or casing inserted in the wall of a building and no provision is made for adjusting the position of the same therein. It is customary to mount a frame in the box containing the board, and with the usual casing employed there is generally left a s ace between the outer edge ofthe board lining and such casing which is both unsightly and dangerous.

With the present type of anel or switchboard mounting it is possib e to adjust the board with the box or frame in the wall so that a neat and tight joint is made between the casing and the board. To the accomplishment of the foregoing and related ends,

said invention, then, consists of the means.

hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms-in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a front elevation of a-panel or switchboard mounted within a casing in a wall, showing my device attached thereto; Fig. 2 is a section on the line 22, Fig. 1;

- Fig. 3 is a top plan view; Fig. 4 is side elevation; Fig. 5 is a section on the line 55, Fig. 4; Fig. 6 is a section on the line 6-6, Fig. 4, Fig. 7 is a section' on the line 77, Fig. 3, and Fig. 8 is a perspective view of the movable adjusting member.

In Figure 1 is shown a box or container 1 usually constructed of metal, which is open pins therefor.

at the front and is retained in any satisfactory manner in the wall 2 of a building. Adjustably supported within the box 1 is the board 3 which is held in position by means of retaining members 4. The retaining member 4 comprises an angular shaped piece 5 whose two sides 6 are at approximately right angles to each other, each of these sides being provided with a lug 7 having an aperture 8 therein, by means of which the member 4 can be bolted to the rear wall of the box 1.

Slidably mounted within the angle formed by the sides 6 of the angular shaped piece 5 is a member 9 against which the bottom 10 and the side walls 11 and 12 of the board are held. The member 9 is shaped as best shown in Figures 3, 7, and 9 having two sides 13 adapted to slidably engage the sides 6 of the angular shaped piece 5 and havin a portion 14 at approximately 135 to each side thereof and connecting them together. Abottom piece 15 is formed integrally with the member 9 and is adapted to be engaged by the bottom 10 of the board to which it is securely fastened in any suitable manner, such as screws or bolts. An ear or projection 16 is formed integrally with and on the same plane as the bottom piece 15, and is provided, adjacent its outer end, with a threaded aperture 17 The members 5 and 9 are slidably held together by means of rivets 18 whose shanks engage in slots 20 in the walls 6 of member 5 and act as guide Projecting from the angular-shaped member 5 and formed by a continuation of the side walls thereof is a recess or inbent portion 21 adapted to retain the projection 16 of the member 9 slidably therein. An adjusting screw 22 is mounted within the recess or inbent portion 21 and is held against longitudinal movement therein by means of a split ring 23 retained between the head of the screw and a shoulder 24 thereon. The

split ring 23 is retained in a slot 25 provided in the wall of the recess 21.

As will be seen in Figure 7, the screw 22 engages the threaded aperture 17 of the projection 16'on the bottom piece 15 of the member 9, the member 9 being moved either away from or toward the rear of the box by rotation of said screw, and is guided by the rivets 18 in the slots 20.

Means are provided for clamping the side t member 9 and consist of a Z a? ozi nately the same shape r potier. of the member 9 and retainer 31 eztending from the erect and adapted overlap co ers of the sides 11 and 12 of the The wall 1 1 of the member 9 is provided v i a threaded aperture 32 which is nted to be engaged by a screw 33 passing ough. a slot in the member and there securely clamping the two side members nd he bottom 10 of the board By means or" this construction it is possible to so adjust the position of the board 3 within the box 1 after it is wired so that the outer edges of each can be lined up and on the same olane thereby making it possible to construct a neat and flush joint between the box and board and the moulding 85, with which it is customary to frame the board in. By this construction it is possible to hang a door from the moulding 35 thereby completely closing in the entir device in a neat and satisfacto'r manner.

will be seen that I liave constructed an eiiicient and simple device for adjustably mounting panel or switch boards and the like as all that is necessary after the board is mounted on the mounting 4 is to turn the screws 22 until the outer faces of the board are in the position desired, after which the casing can be applied and a very neat and finished appearance will have been attained as well as a firm support for the board.

other modes or" applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be emplo ed.

1 therefore particu arly point out and distinctly claim as my invention 1. A panel board support, comprising a retaining member adapted to be placed adjacent the margin of a board, said retaining member having a slot therein, an angular shaped member movable with respect to said retaining member, and having guide pins adapted to engage such slots in said retaining member, said angular shaped member being adapted to support said board, a screw rotatably mounted in said retaining member and adapted to engage a lug on said angular shaped member and clamping means engaging said angular shaped member adapted to retain side members therebetween, said clamping means having a clip thereon adapted to overlap the corners of said side members.

2. A panel board support, comprising a r taining member adapted to be placed adjacent the margin of a board, said retaining member being provided with an inbent portion, an angular shaped member adjustable longitudinally with respect to said retaining member and having a lug integral therewith adapted to slidably fit such inbent portion in said retaining member, a screw rotatably mounted in such inbent portion in said retaining member and adapted to engage such lug on said angular shaped member, and means for preventing the longitudinal movement of said screw.

3. A panel board support, comprising a retaining member adapted to be placed adjacent the margin of a board, said retaining member being provided with an inbent portion, an angular shaped member adjustable longitudinally with respect to said retaining member and having a lug integral therewith adapted to slidably fit such inbent portion in said retaining member, a screw rotatably mounted in such inbent portion in said retaming member and adapted to engage such lug on said angular shaped member, means for preventing the longitudinal movement of said screw and clamping means engaging said angular shaped member and adapted to retain side members therebetween.

Signed by me, this 11th day of July, 1919.

FRED F. HAFEMEISTER.
